OpenSSH: Instalasi Dan Konfigurasi Dasar

Pada artikel kali ini saya akan melakukan instalasi dan konfigurasi dasar openssh server di debian 12.

Topologi

Instalasi

root@srv1:~# apt install openssh-server

Konfigurasi Dasar

Edit file /etc/ssh/sshd_config. Secara default ssh menggunakan port 22 kita akan rubah menggunakan port 2024 dan kita akan menizinkan user root untuk login via ssh.

#Port 22             #baris nomor 14
Hapus tanda pagar dan rubah seperti dibawah ini.
Port 2024


#PermitRootLogin prohibit-password        #baris nomor 33
Hapus tanda pagar dan rubah seperti dibawah ini.
PermitRootLogin yes

Setelah itu restart service sshd.

root@srv1:~# systemctl restart sshd

Uji Coba

Silahkan remote srv1 menggunakan client1 via ssh.

root@srv1:~# ssh root@10.0.0.10 -p 2024
